how to resize pv (pvresize)
i am running redhat on VMware

i increased a disk size from san for existing disk /dev/sdb

how do i resize the disk

Code:
[root@localhost ~]# pvdisplay
  --- Physical volume ---
  PV Name               /dev/sdb1
  VG Name               localvg
  PV Size               15.00 GB / not usable 2.99 MB
  Allocatable           yes
  PE Size (KByte)       4096
  Total PE              3839
  Free PE               511
  Allocated PE          3328
  PV UUID               cwiT8q-V3aL-71LW-SM6V-tv2P-BBvU-Bq3OZ4

Code:
[root@localhost ~]# fdisk -l
Disk /dev/sda: 26.8 GB, 26843545600 bytes
255 heads, 63 sectors/track, 3263 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          38      305203+  83  Linux
/dev/sda2              39        3263    25904812+  8e  Linux LVM
Disk /dev/sdb: 32.2 GB, 32212254720 bytes
255 heads, 63 sectors/track, 3916 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1958    15727603+  8e  Linux LVM

Code:
[root@localhost ~]# fdisk /dev/sdb
The number of cylinders for this disk is set to 3916.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
